Singer-turned-reality TV regular Jessica Simpson appears to have lost her baby weight in time for Halloween.

The busty blonde posted a family shot of herself, fiance Eric Johnson and their daughter dressed up to go trick or treating.

Johnson wore tartan and a wig to hit the streets as Braveheart's William Wallace and the couple dressed baby Maxwell as a cute turkey - but all eyes were on Simpson, who looked stunning as a vampish wench, complete with eye-popping red lipstick, boob-busting bustier, thigh-length boots and pigtails.

Simpson, who posted the family shot on Twitter.com on Wednesday morning, signed up as a spokesperson for diet programme WeightWatchers after becoming a first-time mum in May - and it looks like the plan is paying off.
